Ten Australian ICU nurses` perceptions of organisational restructuring

The Australian healthcare system underwent radical reform in the 1990s as economic rationalist policies were embraced. As a result, there was significant organisational restructuring within hospitals. Traditional indicators, such as nursing absenteeism and attrition, increase during times of organisational change. Despite this, nurses' views of healthcare reform are under-represented in the literature and little is known about the impact of organisational restructuring on perceived performance. This study investigated the perceived impact of organisational restructuring on a group of intensive care unit (ICU) nurses' workplace performance. It employed a qualitative approach to collect data from a purposive sample of clinical nurses. The primary method of data collection was semi-structured interviews. Content analysis generated three categories of data. Participants identified constant pressure, inadequate communication and organisational components of restructuring within the hospital as issues that had a significant impact on their workplace performance. They perceived organisational restructuring was poorly communicated, and this resulted in an environment of constant pressure. Organisational components of restructuring included the subcategories of specialised service provision and an alternative administrative structure that had both positive and negative ramifications for performance.
To date, there has been little investigation of nurses' perceptions of organisational restructure or the impact this type of change has in the clinical domain. Participants in this study believed reorganisation was detrimental to quality care delivery in intensive care, as a result of fiscal constraint, inadequate communication and pressure that influenced their workplace performance.

Nursing care for the families of the dying child/infant in paediatric and neonatal ICU: Nurses’ emotional talk and sources of discomfort. A mixed methods study

BACKGROUND: The majority of in-hospital deaths of children occur in paediatric and neonatal intensive care units. For nurses working in these settings, this can be a source of significant anxiety, discomfort and sense of failure.

OBJECTIVES: The objectives of this study were to explore how NICU/PICU nurses care for families before and after death; to explore the nurses' perspectives on their preparedness/ability to provide family care; and to determine the emotional content of language used by nurse participants.

METHODS: Focus group and individual interviews were conducted with 22 registered nurses from neonatal and paediatric intensive care units of two major metropolitan hospitals in Australia. All data were audio recorded and transcribed verbatim. Transcripts were then analysed thematically and using Linguistic Inquiry to examine emotional content.

RESULTS: Four core themes were identified: preparing for death; communication challenges; the nurse-family relationship and resilience of nurses. Findings suggested that continuing to provide aggressive treatment to a dying child/infant whilst simultaneously caring for the family caused discomfort and frustration for nurses. Nurses sometimes delayed death to allow families to prepare, as evidenced in the Linguistic Inquiry analysis, which enabled differentiation between types of emotional talk such as anger talk, anxiety talk and sadness talk. PICU nurses had significantly more anxiety talk (p=0.018) than NICU nurses.

CONCLUSION: This study provided rich insights into the experiences of nurses who are caring for dying children including the nurses' need to balance the often aggressive treatments with preparation of the family for the possibility of their child's death. There is some room for improvement in nurses' provision of anticipatory guidance, which encompasses effective and open communication, focussed on preparing families for the child's death.

Biomass and energy transfer to baleen whales in the South Atlantic sector of the Southern Ocean

Baleen whales are an important group of predators on Antarctic krill in the Southern Ocean. During the CCAMLR 2000 Survey to estimate the biomass and distribution of Antarctic krill, International Whaling Commission observers carried out a visual line transect survey to estimate the number of baleen whales occurring in the survey area. This paper reviews techniques used to estimate krill consumption by baleen whales and in combination with estimates of whale abundance estimates of krill consumption are generated for the South Atlantic sector of the Southern Ocean. This survey estimates that the present populations of whales feeding in this region are likely to consume approximately 1.6 million tonnes, but possibly up to as much as 2.7 million tonnes of krill within the summer season. Although this only represents 4–6% of the estimated krill biomass in the region (and probably less than this percentage of the total annual krill production), the depleted numbers of baleen whales resulting from past or current whaling activities should be taken into account when setting quotas for the commercial exploitation of krill if there is to be a recovery to pre-exploitation biomass levels of baleen whales.

Multifactorial influences on and deviations from medication administration safety and quality in the acute medical/surgical context

Background and Aims: Although numerous factors influence medication administration, our understanding of the interplay of these factors on medication quality and safety is limited. The aim of this study was to explore the multifactorial influences on medication quality and safety in the context of a single checking policy for medication administration in acute care.

Approach: An exploratory/descriptive study using non-participant observation and follow-up interview was used to identify factors influencing medication quality and safety in medication administration episodes (n = 30). Observations focused on nurses’ interactions with patients during medication administration, and the characteristics of the environment in which these took place. Confirmation of observed data occurred on completion of the observation period during short semi-structured interviews with participant nurses.

Findings: Findings showed nurses developed therapeutic relationships with patients in terms of assessing patients before administering medications and educating patients about drugs during medication administration. Nurses experienced more frequent distractions when medications were stored and prepared in a communal drug room according to ward design. Nurses deviated from best-practice guidelines during medication administration.

Implications: Nurses’ abilities and readiness to develop therapeutic relationships with patients increased medication quality and safety, thereby protecting patients from potential adverse events. Deviations from best-practice medication administration had the potential to decrease medication safety. System factors such as ward design determining medication storage areas can be readily addressed to minimise potential error.

Conclusions: Nurses displayed behaviours that increased medication administration quality and safety; however, violations of practice standards were observed. These findings will inform future intervention studies to improve medication quality and safety.

Mortality and use of the auxiliary score in extensive toxic epidermal necrolysis patients admitted to an adult burns referral centre

 Background: Toxic epidermal necrolysis (TEN) is a rare but fatal condition characterised by cutaneous exfoliation of the dermoepidermal layer and mucosal surfaces. Extensive TEN with epidermal detachment >30% of the total body surface area has been associated with a high mortality. Objective: This study aims to evaluate factors associated with mortality in extensive TEN. In the absence of data to qualify scoring systems such as SCORTEN, this study also aims to evaluate the use of the auxiliary score as a tool for calculating expected mortality. Methods: A retrospective chart review of all patients presenting to our burns service with extensive TEN was undertaken. Application and evaluation of the auxiliary score was also undertaken for this patient population. Results: In extensive TEN, age and delay in admission to a burns centre were factors associated with mortality. Applying the auxiliary score to our patient population, there were no significant differences between expected mortality and observed mortality. Conclusion: Mortality was associated with age and delay in definitive treatment in extensive TEN. Whilst SCORTEN is the gold standard prognostic tool for patients with TEN, in the absence of SCORTEN values, the auxiliary score provides an alternative scoring system to evaluate expected mortality.

How do Thai patients adapt to haemodialysis?

The purpose of the current study was to understand the processes Thai people receiving HD used to adapt to CKD and its treatment. Religion, spirituality, social support and self-management were powerful coping strategies. These coping strategies were strongly influenced by Thai culture and other belief systems.

Impact of high-sensitivity cardiac troponin I assays on patients presenting to an emergency department with suspected acute coronary syndrome

 Objective: To determine whether introduction of high-sensitivity cardiac troponin I (hscTn-I) assays aff ected management of patients presenting with suspected acute coronary syndrome (ACS) to the emergency department (ED) of a tertiary referral hospital. Design, patients and setting: A retrospective analysis of all patients presenting to the Geelong Hospital ED with suspected ACS from 23 April 2010 to 22 April 2013 -2 years before and 1 year after the changeover to hscTn-I assays on 23 April 2012. Main outcome measures: Hospital admission rates, time spent in the ED, rates of coronary angiography, rates of percutaneous coronary intervention (PCI) and coronary artery bypass graft surgery (CABGS), rates of discharge with a diagnosis of ACS, and rates of inhospital mortality. Results: 12 360 consecutive patients presented with suspected ACS during the study period; 1897 were admitted to Geelong Hospital in the 2 years before and 944 in the 1 year after the changeover to hscTn-I assays. Comparing the two patient groups, there was no statistically signifi cant diff erence in allhospital admission rates (95% CI for the diff erence, - 3.1% to 0.3%; P = 0.10) or proportion of patients subsequently discharged with a diagnosis of ACS (95% CI for the diff erence, - 2.3% to 5.4%; P = 0.43). After the changeover, the median time patients spent in the ED was 11.5% shorter (3.85 h v 4.35 h; 95% CI for the diff erence, - 0.59 to - 0.43; P < 0.001) and the proportion of admitted patients undergoing coronary angiography was higher (53.4% v 45.2%; 95% CI for the diff erence, 4.3 to 12.0 percentage points; P < 0.001), but there was no statistically signifi cant rise in the proportion of patients who had invasive treatment (PCI and/or CABGS) (95% CI for the diff erence, - 0.4% to 6.3%; P = 0.08). Inhospital mortality rates from ACS did not change signifi cantly (95% CI for the diff erence, - 1.5% to 0.8%; P = 0.43). Conclusion: The introduction of hscTn-I assays appeared to be associated with more rapid diagnosis, resulting in less time spent in the ED, without a change in hospital admission rates. A higher proportion of patients had coronary angiographies after the changeover, but there was no signifi cant change in rates of invasive treatment or inhospital mortality.

Pd embedded in porous carbon (Pd@CMK-3) as an active catalyst for Suzuki reactions: accelerating mass transfer to enhance the reaction rate

Heterogeneous catalysts are promising candidates for use in organic reactions due to their advantages in separation, recovery, and environment compatibility. In this work, an active porous catalyst denoted as Pd embedded in porous carbon (Pd@CMK-3) has been prepared by a strategy involving immersion, ammoniahydrolysis, and heating procedures. Detailed characterization of the catalyst revealed that Pd(0) and Pd(II) species co-exist and were embedded in the matrix of the porous carbon (CMK-3). The as-prepared catalyst has shown high activity toward Suzuki reactions. Importantly, if the reaction mixture was homogenized by two minutes of ultrasonication rather than magnetic stirring before heating, the resistance to mass transfer in the pore channels was significantly reduced. As a result, the reactions proceeded more rapidly and a four-fold increase in the turnover frequency (TOF) could be obtained. When the ultrasonication was employed throughout the entire reaction process, the conversion could also exceed 90% even without the protection of inert gas, and although the reaction temperature was lowered to 30 °C. This work provides a method for fabricating highly active porous carbon encapsulated Pd catalysts for Suzuki reactions and proves that the problem of mass transfer in porous catalysts can be conveniently resolved by ultrasonication without any chemical modification being necessary.[Figure not available: see fulltext.] © 2014 Tsinghua University Press and Springer-Verlag Berlin Heidelberg.

Restorative care for palliative patients: a retrospective clinical audit of outcomes for patients admitted to an inpatient palliative care unit

BACKGROUND: Restorative care in palliative care is a subset of rehabilitation that aims to improve quality of life through restoration or maintenance of physical functions. Outcomes for restorative care programmes delivered by palliative care units have not adequately been assessed. OBJECTIVES: The objectives are to examine the outcomes of a restorative care programme in an inpatient palliative care unit, including discharge destination, performance status changes and length of stay. METHODS: Retrospective clinical audit of consecutive patients admitted to Calvary Health Care Bethlehem in Melbourne, Australia, principally for restorative care from July 2010 to December 2011. RESULTS: 79 admissions met inclusion criteria. Mean age was 76.5 years (SD=11.14) and 43 (54%) were men. 75 (95%) patients had a malignant diagnosis; of these, the majority had lung cancer (24%). 16 patients (20%) were discharged home, 51 (65%) died and 12 (15%) were transferred. Of the patients discharged home, only 6 (38% of those discharged home) improved their performance status. Those discharged home had a significantly shorter length of stay (17 days compared to 39 days; p<0.05). Patients discharged home also had significantly better Australia-modified Karnofsky Performance Status (AKPS) and Resource Utilisation Groups-Activities of Daily Living (RUG-ADL) scores on admission than others (both p<0.05). CONCLUSIONS: The majority of patients referred for restorative care died during admission, with only a minority discharged home. Patients discharged most commonly experienced maintenance and not improvement in performance status. A successful discharge home following restorative care was associated with a shorter length of stay. Implications and recommendations for successful restorative care will be discussed.
